- Integrated Circuits (ICs) are the foundation of modern electronics; however, manual functional verification is often labour-intensive and prone to errors. This paper introduces a Smart Digital IC Testing System that utilizes an Arduino Mega 2560 microcontroller to automate the testing of 74-series logic gates (AND, OR, NOT, NAND, NOR, XOR), a 555 timer, and a 741 op-amp through a ZIF socket, a 4x4 keypad, and an LCD/buzzer for feedback. The system applies predefined input patterns and compares the outputs against embedded reference values, providing pass/fail results. It incorporates protective features such as current-limiting resistors and voltage clamping. Priced at ₹6040, this system offers high accuracy, portability, and upgradability, making it ideal for laboratories and repair shops. It effectively addresses the shortcomings of previous Arduino/ by integrating mixed-signal verification within an affordable platform.
